双折射材料的温度修正 Birefringent Material Temperature Modification )-)rL@s. iF^qbh%%E 目前,FRED尚不支持“global”温度设置,温度敏感性评估一般用脚本编程来完成,该文档演示双折射材料的折射率随温度变化的问题。附件案例文件包括两个双折射材料模,“KDP”和 “KDP Baseline”, KDP Baseline材料存储在已知温度下的折射率,KDP材料用于储存在“current”温度下的折射率值,定义为与baseline material之间的温度差。一个嵌入的脚本名为“modifyBirefringentMaterialIndex” ,包含在FRED文件中,另外也单独附加。其实现过程如下: -eF-r=FR W-s 6+DY 1.Retrieve the node numbers for the two materials, KDP and KDP Baseline X+XDfEt:Q uS`} 2.User specifies CTE for the ordinary and extraordinary refractive index values as well as the temperature difference from the baseline ?uSoJM`wa! 1 Q(KZI 3.Loop over the baseline material samples and determine the number of wavelength entries Hp=BnN ay7\Ae] 4.Loop over each sampled wavelength entry in the baseline material *gwlW/%Fz $C7a#?YF, a.Modify the ordinary and extraordinary refractive index values using (2) above ,6;n[p"h|r R QQ'Wg b.Apply the modified values to the non-baseline material ^Qx?)(@ O3o^%0 5.Set a description on the non-baseline material indicating the temperature change from baseline =\%ER/ g D6S%O 脚本编程及GUI例程请下载链接: t8-Nli*O ),p0V
